witcher for HDMI 1.3 must be capable of accepting the timings, resolutions

and audio formats of the display that is connected to HDMI output port 1. It is

ecommended that the display with the lowest native resolution be connected to

DMI output port 1. This is to ensure that a compatible video signal will be able
to be displayed on all connected monitors. There is a generic EDID programmed
into the 4x2 Switcher for HDMI 1.3 that can be used instead. See page 10 for

1. EXTERNAL MODE:

ee the next page for details on using the External EDID.

. INTERNAL MODE:

To use this mode, press the EDID button on the rear panel until the front-

anel LED marked “Int” turns bright green. This mode will use a preset

EDID, from the factory, that is stored in the Gefen 4x2 Switcher for HDMI

1.3. This pre-programmed standard EDID data structure is compatible with
most A/V display devices. All resolutions and audio formats specifi ed in
this EDID will be passed to the source device. See the tables below for a

omplete listing of the resolutions and audio formats listed in this EDID.

NOTE: All other HDMI devices/displays connected to the output ports
be compatible with at least one resolution/audio format specifi ed in this
EDID. It is recommended to set, on the source device, a common resolution
and audio format shared by all attached devices/displays. This is to ensure a

ompatible signal is output to all connected devices/displays.
